MAN1B1 - mannosidase alpha class 1B member 1 Gene
Also Known as MRT15; ERMAN1; ERManI; MANA-ER
Species: Homo sapiens
About MAN1B1
This gene has 40 transcripts (splice variants), 272 orthologues, 6 paralogues and is associated with 4 phenotypes. Ubiquitous expression in testis (RPKM 13.4), thyroid (RPKM 13.1) and 25 other tissues.
Summary
This gene encodes an enzyme belonging to the glycosyl hydrolase 47 family. This enzyme functions in N-glycan biosynthesis, and is a class I alpha-1,2-mannosidase that specifically converts Man9GlcNAc to Man8GlcNAc isomer B. It is required for N-glycan trimming to Man5-6GlcNAc2 in the endoplasmic-reticulum-associated degradation pathway. Mutations in this gene cause autosomal-recessive intellectual disability. Alternative splicing results in multiple transcript variants. A related pseudogene has been identified on chromosome 11. [provided by RefSeq, Dec 2011]
